html-in-canvas captures a few things wrongly, and a wrong blurred frame is worse than a sharp one. Add a defect list the runtime checks before it wraps a composition: a WebGL or WebGPU canvas (captured frozen), backface-hidden faces in a 3D context (drawn mirrored), an iframe (reloaded by the wrap and not recoverable), a transform or opacity below 1 on the root (ignored by the capture) and a canvas that is already a capture canvas (nesting hangs the renderer). Any hit turns blur off for the whole composition and the runtime says which one. The backface scan reads rules nested inside a style rule (CSS nesting), sheets pulled in with @import and adopted style sheets. Shadow DOM stays a documented limit. A face whose backface-visibility: hidden arrives through an animation counts too: the scan also takes the elements of running CSS or WAAPI animations that key it, and elements naming a @keyframes rule that does, as candidates. Support Chrome 157's html-in-canvas API alongside the older one: a canvas marked content="drawable" with a drawable attribute on captured children replaces layoutsubtree. Blur, the VFX runtime and Studio's browser check detect both through the new @hyperframes/core/html-in-canvas subpath. Folded review fixes: R14, R9 (the iframe defect entry).

@hyperframes/studio
Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.
Install
npm install @hyperframes/studio
What it does
The studio is a React application with:
- Visual timeline — drag, resize, and arrange elements on tracks
- Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
- Live preview — see changes in real time as you edit
- Composition inspector — view and modify element properties
Development
The studio is embedded in the hyperframes preview command. To develop the studio UI itself:
cd packages/studio
bun run dev # Start Vite dev server
bun run build # Build for production
bun run typecheck # Type-check
Tech stack
- React 19, Zustand 4/5 (state management; development uses Zustand 5)
- CodeMirror 6 (editor)
- Tailwind CSS (styling)
- Vite (bundler)
- Phosphor Icons
